APPARATUS FOR GEN ERATI N G IIO'IIVE FLUID.

-' To all whom it may concern:

Be it known that I, Gnonen B. HAYES, a citizen of the United States, residing at the cit and county of Denverand state of 5 Co orado, have invented certain new and useful Improvements in Apparatus for Grenerating Motive Fluid; and I do declare the following to be a full, clear, and exact description of the invention, such as will 10. enable others skilled in the art to which ,it appertains to make ahd use the same, reference being had tothe accompanying drawings, and to the letters and figures of reference marked thereon, which form a 15 part of this specification.

- My invention relates to improvements in apparatus for generating motive fluid, my ob ec.t being to provide a fluid of this character in which all of the heat units due to combustion are combined in a working medium that can be utilized in a motor without detriment to the cylinders. In doing. this, both the products of the combustion and steam generated by the excessive heat of the 5 products'of combustion, are utilized, both being suitable for motive fluid, preferablyin a combined condition. v

My further object is to obtain complete combustion of thefuel even of a low grade, with as little excess air as possible. This is accomplished by the excedingly high degree of ,heat retained in the cb mbustion chamber and utilized for regenerating the gases. The manner in which the products of combustion are separated-from the combustion chamber also contributes to this end.

The invention relates to that class of -internal combustion generators in whichtlje fuel and air are burning continuously and under constant pressure, while the highly heated products of combustion are delivered to a liquid contained in the generator, and thus diluted with steam and automatically reduced to a suitable working temperature,

a so that. it can be used in the working cylin der of a motor without detriment thereto. Both products of combustion and the vapor of the liquid are utilized, preferably in combinedform, asheretofore stated.

In, my improved apparatus, the combustion chamber is entirely submerged in the liquid which protects the parts exposedfrom the fierce heat of combustion, thus making it racticable' tov utilize the maximum heat ue to combustion. By locating the combustion chamber inside the gener- H Specification of I.etters'Patent. Patented Nov. 15, 1910. Application filed November 1, 1909. Serial No. 525,689.

ator, the internal pressure in the'combustion chamber is counteracted on the outside by the generator pressure, thus rendering it un I necessaryto construct acombustion chamber of suificient strength for withstanding unaided,. the great internal pressure incident to an apparatus. of this character. 7 A

When gaseous fuel is used, a as or-air' compressor and a overnor valve orthe gas are Jequired in a dition to the elements required for liquid fuel.

The fuel feeddevice is designed for automatically regulatini or controlling the delivery of combust1 les to the combustion chamber, as required by the erfect combustion, for various qualities 0 I fuel. v

Assumingthat'a given number of pounds of excess pressure in the fuel and, air receptacles, will deliver the necessary combustibles for'supply'ing the generator when working at ordinary, capacity, the valves may be adjusted so that the combustibles will be delivered in correct proportion for this glven pressure and it' is assumed that the ratlo of air to fuel delivery will for other re'ssures remain nearly enough constant or prac- 1 tical purposes.

The safety valve connected with the gen erator should be set to'go off at a somewhat lower pressure than the predetermined pressure 0 the fuel and air sup ply, whereby a flow of combustiblesis always insured.

. Having briefly outlined my improved construction, I will proceed to describe the same in detail, reference being made to the accompanying drawing, in which is illustrated an embodiment thereof.

In this drawing: Figure 1 is a vertical longitudinal section taken throu h my 1mprovedapparatus, illustrating t e necessary connections for burning liquld fuel. Fig. 2 is a fragmentary section taken through the enerator and the combustion chamber therem, together withsome of the adjacent ele-.:

ments. of the apparatus, the parts being shown ona larger scale. Fig. 3 1s a vertical,

longitudinal-section taken throu h the governor valve, the parts being 5 own on a larger scale.-

The same reference. characters mdlcate the sameparts in all the views.

Let the numeral 5 designate the gemarator provided with a dome 6 and a safety valve 7,

the weight 8 of which should be so adjusted I enerator, and also for delivering them in suitable propor- 'tions for- Y the air compressor is surrounded by a water jacket 16, which is supplied with waterthrough a pipe 17 connectedwith a water tank 18.

The water, after flowing through the jacket 16, passes by way of a pipe 19, into the generator 5, through a standpipe 20, whose upper end is controlled by a float valve 21, acted on by a weighted lever 22.

Within the generator 5, is located a combustion chamber 23, which as shown in the drawing, is spherical in shape and composed of an inner layer 24, of fire clay and an outer layer 25, of metal, or other suitable material. This chamber has an o ening 26, in its top with which is connected a gooseneck-shaped pipe, or conduit 27, which curves u wardly from the combustion chamber, as s own at 28, and then abruptly downwardly, its lower extremity being open and terminating near the bottom of the generator.

Connected with the combustion chamber is a tw-yer 29, through which the air or other combustion-supporting medium and fuel are delivered to the combustion chamber. The outer extremity of the twyer is closed by a transparent lens 30, to permit the inspection of the interior of the twyer, and of the conibustion chamber.

A spark plug 31, is connected with the twyer for the purpose of the initial ignition of the gaseous fuel for the purpose of supporting the fire. The fuel tank 32, has a cone-shaped bottom 33, connected with the twyer by a pipe 34, containing a controlling valve 35. This pipe is also equipped with a valve-controlled nipple 36, whereby means are provided for introducing additional fluid to the twyer throu h the pipe 34.

Leading from t e air-compressor cylinder 15, is a pipe 37', which communicates with a pipe- 38, one extremity of which leads to the top of the water tank 18, while the other extremity is connected with the bottom of a governor valve 39. Also leading from the bottomof this valve'is a pipe 40, which communicates with the top of an air receiver 41. The pipes 38 and 40 are provided with valves 42 and 43 respectively. The function of the governor valve 39, is to maintain the air within the receiver 41 at a predetermined pressure, and this is determined by the tension of aspring 44, surrounding a stem 45, whose lower extremity is equipped with a valve 46. The opposite extremities of this spring act upon a plug 47, and a. piston 48, movable in the valve casing. The spring 44 is set at such tension pass from the pipe 37, through the lower,

compartment 51, of the valve casing and out through the pipe 40, into the air receiver. However, should the pressure within the receiver become too great, this pressure acting .upon the piston 48, will serve to depress the said piston and cause the valve 46, to cut ofl, or partly cut off the passage of coinpressed air through the compartment 51 of the receiver.

The receiver is connected by means of a ceptacle 32, by a pipe 52, provided with a valve 53.

A small receptacle 54, is mounted upon the pipe. 50, by means of upper and lower branches 55 and 56, controlled by valves 57 and 58. This receptacle contains a quantity of fuel 59, for supporting the fire, and when it' is desired to accomplish this pur ose, the two valves, 57 and 58 are opene and a valve 60, in the pipe 50 between the branches 55 and 56 is closed. The fuel within the receptacle 54, is thus placed under the ressure of the air in the receiver-41, where y it is forced out into the pipe 50, below the valve 60, and thus into the twyer 29.

Provision .may be made for producing a spark, or 'a succession of sparks through the instrumentality of the spark plug 31, with.

which the twyer is equipped, as heretofore explained. After the fire is well started, the valve 35, in the pipe 34, leading from the bottom of the fuel receptacle, is opened and ,.the fuel from the tank 32 automatically dei livered to the twyer and thence to the com-' the tank 18, and-also upon the fuel in the I receptacle 32, by virtue of the connections heretofore described. Air is also supplied by the receiver to the twyer for the purpose of startin the fire, this being accom lished through the medium of the small fu rece tacle 54, after which fuel is supplied to t e combustion chamber from the tank 32, l'twyer being surrounded by the liquid witht-h'rough the pipe 34, the valve 35 beingopened for the 1purpose. 7

The receptac e 54:, as used in'the drawing,-

contains gasolene, or other highly inflammable fuel, which may be easily ignited with the spark plug 31 and the flame carried through the twyer 29 and into the combustion chamber 23, and thus used for igniting the heavier and less inflammable fuel with which the combustion chamber is to be supplied later on; and furthermore for heating up the interior wall of the combustion chamher, that the gases of the heavier fuel may substantia junction with the acid.

be easily generated. A large receptacle similar to the receptacle 54 may be used for delivering to the combustion chamber any other suitable fuel, containing a large percentage of combustion-supporting elements, such as liquid air, liquid oxygen or nitric acid When liquid air or liquid oxygen are used, the receptacle should be properly insulated for excluding heat and should-fun.

therniore be equipped with ,a safety valve for releasing any excess pressure which may be generated by the heat which the liquid would absorb from the surrounding atmosphere. When nitric" acid, or other corrosive,

combustion-supporting media, are used, the receptacle and piping should be composed of suitable material for-resisting the corrosive action of the agents *employed. Of course, for some combustion-supporting media, such as nitric acid, the interior wall of=this 'com-' bustion chambermust be previously heated to the proper temperature for disassoci ating the nitric acid and evolving free oxygen.
